stack commented on HBASE-11164:
-------------------------------

There is no support in 0.96 for HBASE-4811 Support reverse Scan.  It was backported to 0.94 but not to 0.96.  HBASE-10018 Remove region location prefetching added making use of reverse scanning doing lookups against meta.  This makes it so we cannot do a rolling restart from 0.96 to 1.0.  Let me add note to refguide.

> I think 1.0 should be rolling upgradable from 0.98 unless we break it intentionally for a specific reason. Unless there is such an issue, lets document that 1.0 and 0.98 should be rolling upgrade compatible. 
> We should also test this before the 0.99 release.
